:"lhis r.invention relates generally to improvements in cash registers and has particular-reference to Aimprovements in the printing mechanisms of such machines.

AIn the accompanying drawings the improvements are applied to the construction shown and described in 'U. S. Patent 1,742,701 granted January 7, 1930 to Frederick L.. Fuller andthe British patents Nto .Frederick L. Fuller, 135,456; 140,363; 157,- 822-3; 157,824 and 157,825 for the same invention. As will be more clearly apparent later on, however, the .improvements'are -capable of. being applied to orfembodied in a numbenof fother forms of cashregisters .and accounting .macliines. withoutdeparting vfrom the spirit of the invention..

A broad object of theinvention is to provide a printing mechanism for printing and issuing checks or printing .upon sales slips inserted to receive impressions, preferably with an automatic device whereby the mechanism may be conditioned for either check printing or sales slip printing.

' Another object of the invention is to provide interlocking devices eiiective Yto insure correct operation of the improved machine as a whole when the printing mechanism is in check printing condition; and automatic 3*) devices by means of which the interlocking devices may be rendered ineffective when the machine is to be utilized for printing upon an inserted sales slip. In the present preferred embodiment the printing mechanism comprises devices for printing certain data including devices for printing the serial or consecutive numbers as well as the date of the transaction upon issued checks.

lilith the foregoing and other objects in view, the invention consists in the novel combinations and arrangement of parts, the features ot novelty of which are pointed out in the appended claims and a preferred embodiment of which is shown in the accompanying drawings.

Fig. Yll is a view showing the slot in the printer frame which coacts with partl of the electro driving devices. i

As shown in the drawings, the machine used to illustrate one embodimentfof the invention is of the key operated type,'that is, various functions, such as, indicating, registering, and printing are eilected directly by operation of the keys. Addition of the present improvements does not materially "affect the operation of such a machine in any of these respects, but when the keys are operated type carriers forming a part of the new mechanism are adjusted to represent the keys and impressions are then taken from the typel carriers upon either'a check strip or upon a sales slip depending upon which kind of printing the machine is repart quired to perform by the nature of the transaction.

In case the mechanism has been prepared or conditioned for check printing, after the keys have been operated and the characters representing them printed on thecheck strip a lever or handle is operated to'feed a portion of the check strip containing the record of the keys operated to a position where it may be severed from' the strip; fjflhe" inserted to receive impressions.

. In the present embodiment,when the machine. is adaptedto print upon an vissued check, an interlocking mechanism'co'ntrol'- ling the sequence of operation of the keys and thecheck feeding mechanismvand printing mechanism is rendered effective.

The present embodiment is'provided with an automatic device in the nature of a vtesting device which controls the unlocking of the `check printing and feeding mechanism. This device is operated during each item entering operation and when a slip has been inserted thetesting device will have no effect upon the locking mechanism forl the check lever so that it cannot be actuated. Toprint upon sales slips all that is vnecessary is to insert slips to a position where they may receive impressions from the type carriers and then depress the keys representing the items. This causes the items to be printed upon the slips, after which the slips are simply withdrawn from the machine. Since the interlocking mechanism referred to is pre- -vented from going into operation by the presence of a slip theI operating keys may be subsequently depressed without necessitating the operation of the check lever.

Vhen, however, no slip has been inserted and a check is desired the absence of an inserted slip will permit the interlocking devices to be effective and will permit the unlocking of the check lever for actuation. After an actuation of the check lever the check lever again becomes locked, thereby preventing a second operation of the check lever until the keys have again been depressed.

Associated with the interlocking mechanism are certain devices for preventing an operation of the check lever while the keys are being depressed even though during the interim the absence of an inserted slip has allowed the testing device to disable one of the locking devices for the check lever.

The operating keys 3() (Figs. l and 3) work inslotsl in the casing of the machine, and are pivoted upon a rod 32 extending across the machine. Resting upon all of he keysis a keypcoupler 33 pivoted between theside' frames 34; of the machine. When the outer'eii'ds' of the'ke'ys aredepressed the key; coupler is rocked clock-wise on its pivot and'eiigages with notches 351 in the rear ,-portionsfofthekeys. The construction and purpose of such key coupler mechanisms are well known in the art `and need not be described-in detail. v f

4Connected to the key coupler 3 3 isal double rack 35 (see Figs.'2, .3 and 4) the connection being'such that as the'key coupler is'rocked by the keys the rack 3 5 is raised and lowered. 'lheY teeth of the doublerack 35 engage a gear 36 (Fig' 2) secured to a transverse shaft 37, first onone side vof the ygear yand then theeotheigin such'a way 'thatA a complete movement offth'e key'coupler, 33 and double rack 35 will effect a con'ip'lete rotation of the gear 36 and shaft 37. The shaft 37 ycarries cams and' otherdevicesfor operating varionsv parts'of the mechanism. This rack mechanismv for effecting rot-ation ofthe shaft has not been described in detail because it is so' old and well known. f

' The' two' keys 38 and 39"(Figs. l and 2) are the keys fortwo clerks or two depart- 1ne1its."""For convenience' they will be referred, to cas the A and B clerks keys. They are connectedwith and operate mechanism for controlling engagement ofl either a'v totalizer4 A or the totalizer B. The particular` construction of the totalizers and the engaging mechanism is not involved in this invention, and is not shown or described in this application. A showing and description of one form may be found, however, in the United' States and British patents to Fuller above mentioned.

The A key 38 in addition to its totalizer selectingor engaging function operates an indicator and does certain other work, but is not connected to devices for setting a type carrier. The machine shown in the prior Fuller application has. however, a type carrier for printing either the letter A or the letter B, and, in addition thereto, a similar type carrier is included in the present mechanism. The position of these two type on the carrier relative to the printing point is controlled by the B key 89.

Journalled in brackets 40 (Fig. 2.) screwed to the base of the machine is a transverse shaft 4l the left end of which has secured to it a cam plate 42 provided with a cam slot (not shown) in cooperation with .afstud43 carried by the B key 39. The construction ofvthe'cam vslot'is suchthat when -theBrkeyfQ isdepresse'd the shaft 4l will be rocked and when the key'739 returns to yits normalposition the shaft 4lwill be 1restoredA to its starting point. For'setting-the clerks? typeucarrier of thel oldI recording mechanism (which is n ot shown'in the present application) there. isprovided asegmental rack 44 (Fig. 2)j pivotedjfupon l'a shaft '45, `theforward end othe A rack'I having 'asuitable link 451 connected to it 'and 'tolaniarmfisecured to the shaft `41 in such o. Wa'ythatfrocking' of the shaft 41l will move the segmental rack 44 Iand directly move the type'ca'rrier from one position to the other. 1 The illustrative machine is 'provided with three-banks of-amount keys nine penny 'keys for entering amounts from-1e to 9, nine dime keys for entering amountsv from 10c to90 and .seven dollar keys'for'amounts ranging from $1.00 to $7.00. These Ikeys are arranged vrto actuate the totalizer elements and set the -type carriers in the new and old recording mechanism fso that anfamount may fbe printedj upon suitable record material Lc?.nlmeI'Isurate 'rv'ith the amount entered E `fl'lhe 'penny ke'y's 'occupy the extreme right hand-vof the keyboard vas lshown in'Figfl, 'severalj 'ofi-heee- .key's "also being' illustrated indligi 39"Ref'e'rring' to 'the latter "figure it'fvlll be Seen that each key 30 is provided fwith an `-11p)vardly extending arm- 47 pro- 'ivid'ed With Ia roller `48.

An electrotype also prints upon the check the name of the company or any additional lmatter such as an advertisement of the establishment in which the machine is used. A sample of the .Work accomplished by the check printer'isillustrateddnFig; 9.

The'printing mechanism for printing 4up- `on fchecks or inserted slips is supported by two vertical side plates 67 and 68, Athe upper rear 4ends of which are supported by a -bolt 69 passing through the ears 71 carried by 'i7 the rear supporting machine frame 70. See

Figs. 3, 4 and 6. 'Thelower rear portion of the side plates 67 and 68 haveextensions 72 projecting into milled vertical slots 73 formed in the portion 74 of the machine frame 70. As best shown in Fig. 4 the vertical .plate 68 extends downward and is suitably apertured to receive one-end of a shaft 75, the other end of .which is carried :by the .'leftniachine frame'34. vSecured torthe in- 'side of the machine .frame 34 by screws 761 '(Figs..2 and 4) is a circular plate 76 vconnected to a .plate 77 by a yoke member` 78 (see Figs. .2, and 6) the purpose of this 'constructionbeing to provide a firm support for'the shaft 75. Y Y As best shown in Fig. 5, Athe forward portion Eof side plate 68 is extended upwardly la't179 and riveted lvto this are the shafts for supporting an electro or printing roller, the .Linking ribbon and its guide rollers, etc. At their :other ends these shafts aresecured 'to 'a'plate/BO as-.best shownin Fig. 3. f It will l'be observed that'a clearance 81 is provided Vbetween the lower edge'of Ithe plate'80 and the upper edge ofthe supporting plate 67. This clearance is to permit the insertion of slips which are to be imprinted and'to facilitate the threading of the check paper.

iThe connections between the type carriers associated with the fcheck or inserted slip printing mechanism and the different diflferentially actuated members will now be described.

f :Atfthefentreme right hand ,end of the shaft'41 which, it will be recalled, is rocked when the B key 39 is depressed, there is secured an arm 82 (Fig. 2) connected as its extreme rear end to the 'lower end of a link 83 (Fig. 5). The link 83 is connected to an extension 84 of a segmental rack 85 loosely pivoted upon the segment shaft and meshing With this segmented rack is a hori- '/.ontal rack 86. The rack 86 as well as the others (Fig. 6) which will be described presently are mounted outside of the frame 68 and are suitably guided in their reciprocable movements by guide studs 87.

The upper and forward edge of the rack 86 is provided with teeth 88 meshing with a pinion 89 (Figs. 5 and 7) secured to a transverse shaft 90 journaled at one end in the side plate 80 and extending through and beyond the plate 68. Secured to the other end of the shaft 90 is a type carrier 91 bearing characters for printing A or B.

Secured by means of hubs 94 to a sleeve 92 -surrounding the shaft 41 are cam lates 93 provided with slots (not shown cooperating with studs 95 carried by each of the transaction keys 59, 60, and 61. The

cam vslots are 'inclined l differentially so :that thevkeys .59, and 61 will rock the sleeve 92 different amounts, In longitudinal alignment with the sleeve 92 is -a sleeve 96, the two` being connected by a yoke 9 71. An arm 97 secured to the4 sleeve 96 .is connected to a link 98 (Fig. 5) which in turn iscon` nected Vto. a segmental rack 99;'(Fig. l6) `meshing with a longitudinally movable rack Ebar 100 similar to the rack 85 andrack bar byLfthe-associated keys will eiect ,correto its various' printing positions.- 4 ff.

At the right end of the tube 116 is secured a segmental rack 117 (see also Fig. 6) meshing with a rack bar 118 which is -in mesh with a pinion 119 (Fig. 7). The pinion 119 is connected to a type wheel 1200 for printing characters representing the amounts 10c to 90 bya tube 120 overlying the -tube 114 just referred to.

For adjusting the type carrier represent" ing the cents registered, there is provided a segmental rack 121 (Fig. 2) which is pivoted upon the sleeve 116 and pinned directly to the cents differential frame 51. The segmental rack 121 is in mesh with a rack bar 122 (Fig. 6) which is in mesh with al pinion 123 (Fig. 7) connected by a tube 1240 to a type carrier 125 for printing the characters representing 1 to 9.

The ink for printing from the diierent type carriers, as well as an electro 124 and prmting type carried thereby, is supplied by an endless inked ribbon 1251 (Figs. 3, 4, and 5) passing below the type vcarriers and electro, around supporting rollers 126 and 128 anda'roller 127 of felt or other Ina-terial capable of carrying an vink supply for the ribbon. The roller 128 is rotatable on a rod l129-support'ed by an arm130vpivoted at 131. A coil spring (not shown) is'wound around this pivot 131, one end beingA secured to the arm 130 serving to maintain a certain amount of tension uponthe ribbon 1251. z

The ribbon is given a step" of :movement at each operationof i the fmachine. This not only prevents successive .impressions through the sameportion of the ribbon,:but

it alsoservesto bring'the different portions.-

of theribbon into 'Contact 1with thefroller 127 and thereby lpermit it-.tov moistenor -applyl ink tothe ribbon." -Thisi-mechanism is best shown 'in 'F-igs. l4 andhr Secured -to the shaft 1311 which supports-,the inking' roller 127is a ratchet disk 132, the teeth of which are f engaged by' afspring-pressed loose lon 'the shaft 1311.A The armv 134 vis connected by'a link 135: -to a short bell crankI 136 loose'on'the tubez1240 the' horizontal arm of the said bell-cranlrbeing connected by a link 137 toa second bell crank 138'pivoted at 139 outside of the` `vertical side -platey 68. One arm of th'efbell crankis provided with a roller 140f'in -co-dperation 'with a cam slotl formed'ina boi cam 141'ca1ried-by therotation sliaft *37.* The shaft 37 ,f -itf rwiil fbe recalled4 makesa complete rotation at each operationof the machine and tliemechani'sm` impression block 143 of rubben or other.v

Suitable material and of sufficient lengthto take an impression from'all the type carriers.` As best shown in Fig. 6, the hammer 142'is supported by arms 145 Aand 146 journaled-in the vertical side plates67 and 68 respectively.

Printing movement is iparted to the im'- pression hammer by an arm 1461 (Fig. 3) pivoted at 147 to the side plato-67. The forward edge of the arm 1461has a shoulder 148 engaging a downward extension 149 of the arm 145 previously referred to. Near its lower end the arm 1461 carries a rollerthe type. This printing movementv is 'effect-l ed at substantially the end of the downward stroke of the keys at which time the type carriers are retained in their adjusted positions. 'l

To suitably align the type to print along a horizontal line, a plurality of alignin pawls 153 (Figs. 4 and. 5) are provide These pawls are rigid together and are mounted loosely upon a rod 154. In order to rock the pawls into engagement with the pinions to align the type advantage is taken of the movement of the link 135 associated' with the inking ribbon feeding mechanism. As best shownin Fig. 4 one of the aligning pawls'is bifurcated at its upper end to engage a short'studf 155 carried by the link 135, so that the reciprocating movement'of the link will move the ypawls in and-out of engagement with the type carrier pinions. The checks printed and-issued by the ma-` chine are drawn .froma roll 156.,.(Figs. 3, 4, .and 6). of 'paper or other suitablemate-l riallooselysupported by a rod 157 'having-g its ends .engaging slots1571 in the side plates 67 and 68, the construction being such that the' roll ofrpaper may be readily withdrawn (ir-a new onev readily inserted for replen-` ishing the paper supply. vThefs'trip passes from the supply roll 1561-between the inking Y-ribbon 1251.1 and impressionl bloclri143, under the electro 124 andbetween a roller 158 and `159 .andl into receptacle 1600'formed in the cabinet of the machine. The roller 159 is journaled -between 'two spring-pressed arms 160 and 161 connected by a cross-barv 162, the lower ledge of which is formed to serve satisfactorily asa tearing guide for the check strip. 1 1

A Reference has been made heretoforei'to an electro 124 which is adapted to print -a consecutive number and date besidesv additional matter as shown in Fig. 9. The electro is given a full rotation during each reciprocation of a check handle by means which will presently be described, and is adapted to feed the check out of the machine. The dating wheels are contained within the cylindrical electro, and in axial alignment with these type wheels are the consecutive number wheels, the units order of which is actuated during each check-feeding opera-- tion'to add a unit to the number standing upon the wheels. Such mechanism is well known in the art, but for vfurther information as to the details of construction and operation reference may be had to patents to Carney, #497,861 and Wells #1,151,747. The electro 124, as previously stated, nis given a complete rotation duringeach operation of a check issuing lever 165 and the means for accomplishing this will now be set forth.

This mechanism is best shown in Figs. 5, 6, and y8. Loosely pivoted upon a hub integral with the side frame 34 and in lon- ,f jfitudinal'A alignment -iwithr the segment shaft" :,'is allever165, the upper end of. which protrudes-.through a slot in'the casingand is provided with a handle for externalfma nipulation thereof. Thecheck lever '165.-f`is provided with a forward extension 166 Fig.- 6).-vconnec ted to which is a link 167 Fig. 3*).- ywhich in turn is connected to. an arm 168 securedto the. shaft 7 5, previously referred tof.J Secured .to the shaft is a segmental rackw213 in continuous mesh with a driving Pivoted tothe gear pinion172 is a feeding, pawl;1731(see Fig. 8) provided with a stud. 17,4:Qwhich co-operates with, av circular-slot.. 175'formedin the printer side frame 68.;

vThe feeding pawlv17'3 is provided with a."

projection 3 normally engaging fthe radial shoulderlof the notch-171 in the shaft 171) preniou'sly mentioned and is, normali fspring-'pressed' into engagement therewit byafpawl 176 ,pivoted to the printer side frame 68, `the-movement of the pawl 1176;

being limited by av pin; 1712 carried bythe frame 68..,:The stud-174 is adapt-ed to' be Tcammed at certain times into ico-operation Withan .eniarged'or clearances portion 177. of the;:slot ,-175. In order .to prevent retrograde movement of the roller 15,8.fthere ispivoted' to the frame 68 a springpressed pawl 178. y

The operation of the parts just described is as follows: Inorder to feed a check out of the machine, the check handle 165 is moved rearward, the segment 213 thereby rotating the shaft 170 clockwise as viewed iniFig. 8. The rotation of the shaft 170 will, due to the engagement of thepawl 173 with the radial shoulder of the notch 171 rotate the ratchet wheel 1711, gear pinion 172 and roller 158, thereby feeding the check out of the machine. As the gear pinion 172 is rotated from the position shown in Fig. 8T the stud 171 of pawl 173 will engage the concentric portion of the slot 17 5 and positively hold the engaging end of the feeding pawl in co-operation with the notch 171 of the'shaft until tha shaft and parts carried thereby are giveny a full rotation. 'At this time the check lever is now in its extreme rearward .position and the parts on shaft 170 are again inthe position shown in Fig. 8. Upon drawing the check lever forward the shaft 170 will be rotated counter-clockwise as viewed in Fig. 8, the non-radial portion ofthe; notch 171first camining the; pawl forward-,fthe :studi 17a then entering the clearance portion :of the 'slot-'1717... As the check flever. is returned toaits normal :posi-1 tion the .spring-pressed Ypawl 176 :will constantly urge the feeding pawl 173` rearwardly until the shaft again returns vto its normal position, whereupon the engaging end of. the pawl will snap into the notch 171 formed inthe shaft 170.

Y As stated. previouslythe present, embodiment is adapted to print upon inserted slips, the presence of a slip preventingfthe operation of interlocking :devices between the operating'keys and check lever, thus'allowing repeated operations of .the ke s Without requiring acheck to be issued. `o control the interlocking mechanism a testing device has beenprovided.1.v i

This mechanism is best: shown 1in Figs., 4, 5 and' 6. 1 The testing device is operated dur ing each operation of the machine and comprises an; upwardly'extending arm 200 secured-to the key coupler-33 and provided with a studu201V .engaging a bifurcation .of the lower armi o f afbell crank 202. v As shown in Figs,- 21and 4the belli crank 202 is pivoted to then sidefframe-B by ay stud 2.03,v and'has a forwardlyvextending arnr204. f;

It and 6) which is provided with an lelongated slot 2081tozfreceive'thefportion 207 when the latter is `moved upwardly if it is not stopped by the presence of a sli Sales slips are inserted in slot 2000 forme in hood 2001 of the cabinet which slips: then assume a position between the plate 208 and the upturned portion 207..v It may be noted that the sales slips are composed of paper having siilhcientv rigidity to overcome the tension of spring-.212,thuspreventing the portion 207 from moving past the said slips during the slip printing operation of the' machine. The tension` of spring 212is adjusted sothat it is just suilicient to effectively perform the function of lifting the member 205 during the regular operations of the machine. Thus, it is clear that the ordinary paper used for sales slips is sufficient to overcome the tension of this spring. As is clearly shown in Fig. 6, vthe testingdevice is disposed at one side of the check paper 156.

For communicating motion from the bell crank 202 to the testing' device the following construction is usedff'lhetesting deviceis. provided with integral ears 209 (Fig. 5) in which is inserted a plunger 210 havingf a lower'head. port-ion. 211; contacting with the upper edge` ofthe forwardly extending arm 204 of the bell-crank 202. A spring 212v forces the plunger 210 downwardly to hold its head 211 in engagement with the arm 204.

From the foregoing it is clear that when the coupler 33 is rocked during operation of the keys the stud 201 will impart a movement to the bell crank 202 and that the arm 204 of the bell crank will force the plunger 210 upwardly. The vertical plate 207 will contact with an inserted slip and .prevent any further vmovement of the testing device 205 and the spring 212 will be compressed during the rest of the l'movement of the key coupler.

V1t is, of course, evident that if no slip is to be printed upon a check must bey issued.`

The absence of a slip in the machineper mits the following to take place: release the check lever for operation, prevent a move-- ment of the latter until the keys are returned te normal, prevent a. second operation of the keys until the check lever has been operated and a check issued, and restoration ofi-the parts to their normal position. A-These will be taken up in the order named.

The actuating segment 213 is provided with two locking lugs 214 and 215. The lug 214fnormally is immediately forward ofa locking member 216 pivoted upon the forward end of the testing device 205 so that it locks the check lever againstl operation. Formed in the lower edge of the testing device 205 are two square shoulders 217and 218 either of which is adapted to engage a lug 219 formed at the'upper endof a. bell crank 220 pivoted at 203. The lower end of the bell crank is in engagement with a lug 221 integral with a locking arm 222 loosely pivoted upon the shaft 75. A spring 223 tends to move thev bell crank 220 counterclockwise as viewed in Fig. 5 so that at certain times the lug 219 will co-operate with the shoulder 218.

It" no slip is inserted in the machine and the keys are depressed, the vfollowing operation will take place: The rocking of the arm 204 will move the plunger 210 upwardly and since a slip has not been inserted the testing device 205 will move upwardly the full distance, the spring 223 rotating the bell crank 22 counter-clcckwise until lug 219 rests under the shoulder 218 to retain the testing device in its upward position.

The locking member 216 is now out of the path of the lug 214 thus permitting an operation o the check lever; but it will be remembered that while the testing device was being actuated the forward edge of the arm 204 passed to the rearward of the lug 215 thus preventing any operation of the check lever until the keys are returned to their normal position. Then the keys are returned to their normal position, the check lever is unlocked, permitting the issuance of a check upon which has been imprmted the value of the keys and 4other-identifying chari acters. v

It is, ofcourse, desirable that when the machine 1s placed 1n a condition -for 1ssu.

downwardly to rotate the bell crank 220z counter-clockwise the rear end of .locking arm 222rfdrops front ofy thestud 201 car-- ried by the arm 200 previously referred to when that armwreturns :to the normalA position :shownrin Fig'. 5. This will ,blockvany attempted movement of the coupler: and-pre.v vents-'the'keys rombeing'operated until acheck has been issued.

'Itwilh ofcourse, .be necessary :to return? the parts to their normal position shown 'in' Fig. 5 after a check has been issuedi. ,For accomplishingthis the ollowingfhas been provided :l

As shown in the'plan-viewfof Figf the bell crank 220-is provided with a second lug 224 which is slightly longer than the'lug 219 previously mentioned and it-should bev noted that the lug 224 is in the plane of the actuating segment 213. When the segment 213 is moved rearward from its position shown in F ig. 5 it will contact with the lug 224 and drive the'bell crank 220 rearward until the lug 219' is brought under the shoulder 217 .v This will vallow the testing device to drop downward by virtue of its own weight and when the segment 213 'has been returned to its normal position the locking member 216 and lug 214 will be brought into locking engagement preventing a second operation of the check lever without an intervening operation ot the keys.

It will be obvious that the locking arm 222 is also drawn upwardly during this operation bringing it out of the path of the stud 201 at the position shown in Fig. 5 thus Vpermitting the keys to be depressed.

It will be seen that this mechanism provides in a very satisfactory manner a means for eifecting the desired results; that is, lto permit the operation of the check lever only when a check is desired and to prevent any fraudulent or irregular operationsof the machine.

In describing the construction of the improved machine it has been necessary incidentally to describe the operation of the varions features to such an extent that it is thought that the usual summary of the operation of the machine may be omitted.
